Gosl  Go scientific library
Gosl is a set of tools for developing scientific simulations using the Go language. We mainly consider the development of numerical methods and solvers for differential equations but also present some functions for fast Fourier transforms, the generation of random numbers, probability distributions, and computational geometry.
This library contains essential functions for linear algebra computations (operations between all combinations of vectors and matrices, eigenvalues and eigenvectors, linear solvers) and the development of numerical methods (e.g. numerical quadrature).
We link Gosl with existent libraries written in C and Fortran, such as OpenBLAS, LAPACK, UMFPACK, MUMPS, QUADPACK and FFTW3. These existing libraries have been fundamental for the development of highperformant simulations over many years. We believe that it is nearly impossible to rewrite these libraries in native Go and at the same time achieve the same speed delivered by them. Just for reference, a naive implementation of matrixmatrix multiplication in Go is more than 100 times slower than OpenBLAS.
Installation
Because of the other libraries, the easiest way to work with Gosl is via Docker. Having Docker and VS Code installed, you can start developing powerful numerical simulations using Gosl in a matter of minutes. Furthermore, it works on Windows, Linux, and macOS out of the box.
Containerized
 Install Docker
 Install Visual Studio Code
 Install the Remote Development extension for VS Code
 Clone https://github.com/cpmech/hellogosl
 Create your application within a container (see gif below)
Done. And your system will "remain clean."
[](zdocs/vscodeopenincontainer.gif)
Debian/Ubuntu GNU Linux
First, install Go as explained in https://golang.org/doc/install
Second, install some libraries:
sudo aptget install \
gcc \
gfortran \
libfftw3dev \
liblapackedev \
libmetisdev \
libmumpsseqdev \
libopenblasdev \
libsuitesparsedev
Finally, download and compile Gosl:
git clone https://github.com/cpmech/gosl.git
cd gosl
./all.bash
Done. Installation completed.
Documentation

(see each subdirectory for more information)
For the sake of maintenance (see next section), we have removed the previous mpi
subpackage. However, we recommend the external library gompi if you plan to use MPI.
Previous version
The previous version, including more packages, is available here and can be used with the Docker image 1.1.3 as in this hello gosl example.
These other packages, such as machine learning, plotting, etc., have been removed because they do not depend on CGO and may be developed independently. We can now maintain the core of Gosl more efficiently, which has a focus on the foundation for other scientific code.
